To all whom 'it may concern: form air spaces in the Be it known that I,Goi'rnan'r Tnnnnnfr, a citizen of the United States, and'a resident ofPittseld, in the county of Berkshire and l cores which serve tocompleted wall and raising the mold sections and the c ore step by stepas the Wall is built State of- Massachusetts, have invented a new l lnthe specific construction illustrated, and Improved Mold forConcrete-Wall Con- I each mold section 10 is formed ofav sub.-struction, of which the following is a full, stantially rectangularframe l1 of Wood or clear, and 'exact description.

stay bars l1il and having a face plate 12 Se- This invention relates tocertain improvements in molds :tor concrete Wall construction, and moreparticularly to means for l concrete while the latter is hardening. Thisface plate is referably of metal and may be either smootii or 'embossedsurface of any suitable form to give the nished concrete `wallappearance, as illustrated at 12 in Fig. 8. For supporting and raisingthe sections, I provide a plurality of vertical standards 13' adapted tobe embedded Within the wall andextending upright therein intermediatethe mold sections. Each upright is somewhat tapered in cross section, asis clearly illus trated in-Fi s. 4 and 7, and is located adjaf cent oneof t e cores, whereby after the wall- "has been completed to the desiredheight and the core removed, the upright may be moved .laterally intothe passage formed by the core and then may be removed entirely from thewall. As illustrated, each standard is provided with oppositely-disposed perforated metal face plates 14, which are engaged by theraising mechanism and serve to protect the wooden body portion of theupright. As shown, the supports for the mold sections comprise a pluiaity ofsubstantially vertical rods 15, each in rigid engagement with theupper and lower sides of the' frames of the mold sections and each endbent inward to a point adjacent one of the uprights. The two rods` arepivoted together at this-point*` and connected tdthe raising mechenisinwhich surrounds the upholding the mold sections in engagement with theWalls and for raising them step by step as the Wall is built up. Myinvention also involves certain construction in collapsible cores to beused in connection with said molds and coperating with the support forthe'- mold sections to permit the'. latter. l l

e invention consists in certain features of construction andcombinationsv of parts,

the removal of after and claims. l

Refereneeds to'be had to the accompanying drawings, fornuinpf a part ofthis specifi particularly pointed out in the ence indicate correspondingparts in all the ligures, and in Whichn Figure 1 is a top plan view of awall in process of construction and illustrating one embodiment of myinvention; Fig. 2 is a side'elevation of one corner of the structureshown in Fig. 1, and on an enlarged scale; Fi, 3 is a transverse sectionshowing the nio d and core after having been raised for the constructionof a second section of the Wall, said vieiv being taken on the line 3MBof Fig. 4; Fig. e is a top plan view showing the mold core and raisingmechanism on an enlarged scale; Fig. 5 is an inverted plan view of thevcore; Fig. 6 is a side elevation partly' `in section, showing themold-raising i right and serves for lifting the latter when a is a planview of a corner section of the wall has been completed.

This connecting mechanism provide oppositely-disposedpreferably comprises a cross bar lo having mold sections spaced apart tothe desired one'eud pivoted to one of'ihe rods 15, and distance andadapted to support and hold having the opposite cnd'pivoted to a leverthe concrete in lace While it is hardening to 17, one end of which ispivoted to the tippeform a Wall. l ithin the mold are providedsitely-disposed rod l5. The bar 16 is pivotmeans are provided for thedesired cured thereto and adapted to support the i or present a gureduneven'- having its upper ed to the lever at a short distance from thepivotal support of the latter, and by .the movement ci? thellever thesections may be brought toward each other to the desired position or maybe spaced apart and separate from the completed wall. lilith the leverextending out Yardly, illustrated in Figs. 3 and d, the sections areheld rigid in respect to each other, but when the lever is raised, eachof the two sections is inovcdi'orward and out ot' engagement with thewall the sections hein'g supported by the vrods 1, the upnrr ends ofwhich are connected to the corresponding upright 13. As the ujper endsof the rods 15 arc connected together and the har l'co'nnects themintermediate their ends, it is evident that the lower ends are also heldrigid in respect to each other, but to prevent any possible bending ofthe parts and to hold the lower portion lof the mold sections in lirmengagement with the portion ot the wall just completed, l may, it'desired, provide a tie-bar 1S having an operating handle 18 at one endthereof, and having the opposite end threadedi'or the rcception of a nutin engagement with the 0pnosite mold section. By tightening this tie'-bar, the 'lower ends of the section are positively prevented fromspreading apart from the pressure of the concrete.

For raising the mold sections, I provide mechanism in engagement withthe upper ends of the rods 15 and with the uprights, and having suitablehandles for operating the saine, whereby the sections may be. read-- ilyraised irresliective of the weight thereof. As illustrated, thismechanism comprised a rectangular' frame 19 having gripping arms 2O and21, pivotally connected to the opposite ends thereof, each of the armsinelosing the upright and engaging therewith at the side opposite to itspivotal support. Each arm is provided with an inwarally-directed toothor projection adapted tol enter one of the pertorations of the faceplates 14 on the uprights, and the upper ends ol' the two arms areconnected together by a suitable coil spring Q3. rllhe 'trame 1S) isprovided with handles and 525 extending cui wardly therei'rci'n inopposite directions, and by .means ot these handles the .traine may berocked to cause the gripping arins to engage at successively higherpoints on the opposite sidesot the upright, and thuslit't the entireraising mechanism and the mold sections connected thereto. The traine15) pio vided with depending plate Qt? at one sido thereoi", and tothisplate are pivotally con-- nected the two oppositely-disposed rods 1.The plate is provided with suitable, lian; is QT engaging with theopposite sides ot t ie upright to hold the plate in a .saibstantially'vertical position and prevent side movement thereof in respect to theupright.

siegel In the operation of the raising mechanism, the teeth of the twogripping arms engage in recesses in opposite sides of an up right, andby raising one of the handles,' as, for instance, the handle 2li, thegripping arm 21' is raised along the side of the upright to the positionillustrated in dotted lines. During this upward movement of the arm 21and handle Q41-, the entire weightoil thefafall sections is supported bythe arm The handle 25 is then raised and the tooth of the arm 21 engageswith the upright and the entire wall section is raised and the grippingarm 22 is also raised to a higher point on the side of the upright.Before raising the mold sections, the lower tie-rod 18 is lirst removedand the lever 17 raised to spread the mold sections apart. When the moldsections have been raised te the desired height, they are againbroughttoward each other by the lowering oi the lever 17 and the lower ends arefirmly bound together by 1the insertion oi the tie-rod, 18. rllhe smalltransverse opening left in the wall by the removal of the tie-rod 18 mayreadily be filled with concrete from both ends thereof to conceal thesame from view.

In connection with the mold sections and raising mechanism abovedescribethl preferably provide a plurality of cores serving for theformation of' air spaces within the completed wall. he cores may be ofany desired shape in cross section, out are preterably formed withrounded ends and straight sides, as illustrated in the drawings.

The top of each core is formed oit a plate 'QS oit the desiredshape,-and the sides and ends of the core are preferably formed of vsheetmetal walls 29 similar to the sheet metal walls of the mold sections. Atthe bottom of each core, I preferably provide blocks 30, to hold thecores in the desired position, and between the opposite side walls 29means is provided for drawing these walls together and partiallyeellapsing theI core to facilitate the removal thereof from the wallafter the concrete has hardened. As illustrated, .this collapsing mea'nsincludes a rod 3l extending vertically through the central portion ot'the core, and having a plate rigidly secured to thedower end thereof.This plate is provided-with two crm slots 33 for the reception of pins3i carried by the mold sections at their lower ends. By rotating the rod31 the pins are caused to tra-vel inwardly or outwardly' due to thecurvature of the slots, and the slots are so 't'ornied that the partswill remain ineither the extended or the collapsed position. By drawingthe side walls of the core together, illustrated in dotted line in Fig.5, the width of the core is redu'ced to a mat .rial extent and thecurved end portions of the core are also brought `somewhat,nearertogether: With the core thus reduced iii cross section, it may bereadily removedfroni the hardened concrete about the saine and maybereadily raised with the mold sec-` 6 tions. 'The upper end of the rod 31is pret- I erably rigidly connected to a transverse supporting bai'- 35,which enga es lwith the up r' siirface of the' opposite -y disposed' mod sections for supporting the core, and is '10 preferahlfyof springmetal to permit of the raisingo the ends of the bar out of engagementwith the mold sections to rotate the berend the rod 31 and to collapsethe core.

Where it is desired to form a corner in the '1 5 wall, I provide meansfor rigidly securing together the outer mold sections which meet attheangle, and provide means to facilitate 1 the uniting-1 of the innermold sections at the inner side of thewall. One of the outer moldlsections nt the corner is provided with v perforated lugs 36 at theupper and the ower edges thereof, and the other mold section coperating"therewith to form the corner is provided with locking mechanism Vadapted for en agement with these lugs. As

illustrated in ig. 2, this locking mechanism comprises two pivoted arms37 adjacent the upper andv the lower sides of the/mold sections and eachhaving an outwardly-ex A tending dog or projection adapted for engagmentin the perforation of the corre- .sponding rejection 36 of the othermold section. o each of the arms is pivotelly connected a link 38, andthe inner ends of, '85 the two links are connected to an oscillating tmember 39. By oscillating the member 39, the linkseare drawn inward orforced out- WardA to iemove vthe arms from engagement vwith the lugs orforce them into such en- 40 gagementto lock the mold sections togetherIor to separate the seine. At the inner corner of tlie'wall, erich ofthe inner mold sections is formed lof such a' length that the sectionsdo not ineet'when the mold is in place for the reception of theconcrete, but the gap between the two endsv is closed by a verticall-disposed angle-iron 40, as illustrated in iigs. l and To facilitate theremoval of the uprights after the wall has been completed to aconsi'derable height, -l provide certain of the cores with ends of sslightly greater Width than the width of the uprights, and 1n engagementwith the sides of said upri hts, as

illustrated more clearly iii Fig. 7. W en the wall hns been huilt up tothe height of the upright, the cores adjacent said u rights are entirelyremoved, sind due to tie tapered forni of the uprights, they may bereadily movedlnterully into the hollow space in the wall which wasformed by the core. The upright mayy then be raised out 'of the wall andsupported on to thereof to serve for the further raising o the moldsections.
